Magnum swap w/ A-833

there is a plate you can get here to balance it as well, I got one from Lordco, I think it was made by Mr. Gasket, I cant seem to find the one I had but I could look for the part number later if you need it and it was cheap, like 25 bucks or so, I believe it actually came out of Mopac in Langley B.C. to Lordco


Maybe was it the Mcleod 450016? I can't find enough info on it to know if it will fit my oem 130 tooth flywheel?
